Zhang Huan, an electrical engineer in the high-speed wire rod mill of Nangang, is one of the best electrical experts in Nangang. For more than 20 years, he has always followed the pace of automation and upgrading, making outstanding contributions to the progress of Nangang's automation and control. As the head of the transformation of the high-speed line factory, he promoted a production line with equipment level in the late 1980s to the most advanced wire production line in the world today. In the technological transformation of the large coil of Nangang Group, Zhang Huan independently designed a complete set of automatic control procedures and completed the commissioning, creating a precedent for localization of large-scale coil production lines in the country and saving millions of R & D and design expenses for enterprises. The first domestically produced large coil production line independently designed by his team won the second prize of scientific and technological progress in Jiangsu Province and applied for a number of national patents. In the steel reduction project of Nanjing Iron and Steel Group, he organized and implemented only 30 days, creating the fastest record of the same type of technological transformation at home and abroad. After Zhang Huan Model Studio was established in 2009, he gave full play to the leading role of model workers, leading the radiation role and leading 10 young technicians. Production personnel continued to carry out scientific and technological innovation and other key scientific and technological innovation activities. In 2011 alone, 16 technical research projects were completed, creating a profit of 10.5 million yuan. Has won the "National May 1 Labor Medal", "Jiangsu Province model worker" and other honors, the Ninth "Top Ten Jiangsu Province, civilized workers."

Improvements in the technology for the enhanced exploitation of oil and gas fields has increasingly required the use of long continuous lengths of stainless steel and nickel alloy tubulars for hydraulic control, instrumentation, chemical injection, umbilical and flowline control applications. The benefits of this tubular technology have resulted in reduced operating costs, improved recovery methods and reduced capital expenditure by connecting downhole valves and chemical injection with remote and satellite wells to a fixed or floating central operating platform.
